UNITED STATES SPECIFICATION forming part To all whom it may concern: I

Be it known that l, GEORGE RAMSDELL, of Oswego, in the county of Oswegoand State of New York, have invented certain new and usefulImprovementsin Manufacture of Gas; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanyin g drawings, and toletters of reference marked thereon, which form a part of thisspecification.

pond, in the combination, with an. air-pressure feed-tank and anoil-retort, of a connectingpipe provided with an inclosing-pipe and anannular packing of asbestus interposed Joetween the two pipes.

Eeferrin g to the drawings, Figure l is a view, in front elevation, 'ofa bench of retorts embodying my improvements. Fig. 2 is a de-. tailview, in vertical longitudinal section, of the supcrheating-retort. Fig.3 is a similar view of the hydraulic main. Fig. 4 is a detail sectionalview of the three-way valve and its connecting parts. Fig. 5 is a detailsectional view, representing the feed-pipe in its connec tion with theoil-generatin g retort.

The bench may be made with any desired number of wood and oil retorts.

The wood and oil retorts A and B are re spectively provided withstand-pipes G, having heavy seals a in their connection with thehydraulic main- D. The lower retorts connect,

by short intermediate pipes, E,with the upper retorts, and'the latterrespectively communicate with the two converging pipes F. Thesuperheatin g-retort G communicates with a pipe, G, which connects withsaid converging pipes. A three-way valve, H, located at the junction Myinvention relates to certain improvements P TENT OFFICE.

of the three pipes, controls the connection of the superheating-retortwith the gasgenerating retorts.

By these means the gas can be independently shut off from either sidewhile charging the gas-generating retorts; or the gas can be shut oiffrom the superheating-retort and be conducted up through stand-pipes 0while carbon is being burned out of the superheating-retort; or the gascan be shut off from either side while carbon is being burned out of thegenerating-retorts on the opposite side. At the same time gas from thegenerating-retorts which are not being burned out can be passed up intothe superlieating-retort. This latter retort is formed with upper andlower horizontal compartments, 1) 0, respectively pro-' vided with doorsd e. The wood-gas and oilvapor, being united in the lower compartment,pass rearward through the latter, thence into the upper compartment andforward, to be discharged as a fixed gas into the stand-pipe K. Thisstand-pipe is provided with a light seal, f, in its connection with thehydraulic main. The difference between this latter seal and seals a issuch that the gas or vapor from their respective generating-retorts isprevented from passing through stand-pipesO, while the three-way valvepermits free passage into the superheating-retort. The stand-pipes aremade vertical in order to obviate, in large measure, the tendency toclog and obstruct these passages, caused by depositions of carbon.

Dip pipes K connect directly with their respective stand-pipes andextend in lateral inclination therefrom to the hydraulic main. Thesedip-pipes are made straight, thereby preventing the deposit of carbontherein, and also permitting them to be readily cleaned.

The dip-pipe which connects with the stand- 7 pipe.

The oil-gas-generating retort is connected with theair-pressurefeed-tank L by an intermediate pipe, g, connecting with itsrear upper portion. An inclosing pipe, h, surrounds thisconnecting-pipe, and an annular packing of asbestus, Z, is interposedbetween the two pipes. The oil-conducting pipe is in this mannerprotected from the heat, and also is prevented from having deposits ofcarbon accumulated therein. This oil pipe passes from the retort upthrough the arch to the oiltank, and may be provided with valvemechanism. The inclosing-pipe h is seated on the oil-retort within aringsetting, m, and packing n secures it in position.

The air-pressure feed-tank connects with a suitable oil-pump andair-pump.

Thehydraulic main is provided with a door, 1), at the lower portion ofone end, for purpose of readily cleaning the main.

Having fully-described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with generating-retorts, stan d-pipes, anddip-pipes, which latter extend a considerable distance into thehydraulic main,

of a superheating-retort connected by interine- GEORGE RAMSDELL.
